Seeking solution to deal with hardness of water

Finding a solution to high levels of hardness of water


We have extremely hard water of TDS 1500 and hardness 700 mg/ltr. We have a softener installed but it is not giving satisfactory results . A local technician informed us that softeners do not work with well water with this high hardness. Is this true? What is the solution for this? We have an RO installed for drinking purposes, but need soft water for other purposes mainly for residential use in the house. Please also suggest a good company that offers these services.
